BACKGROUND OF INVENTION

With rapid development of industry and commerce, various industrial productions and human business activities are frequent and concentrated. Due to smoke emitted by industry and vehicles, such as automobiles, the pollution of water, sunlight and air that humans depend on has had a serious impact on human health. At present, there are various kinds of invisible substances in the air due to serious pollution. For example, a large concentration of automobile exhaust gas, fine dust particles, hair, fibers, and various industrial pollution gases float near the ground. Therefore, it is easy to continuously inhale these harmful substances in various places and spaces, and various diseases are caused.

In addition, many countries have faced high concentrations of PM2.5 pollution in recent years. The public is concerned that PM2.5 pollution may cause serious harm to the health of their families. Therefore, we need to rely on the use of air purifiers at home or in the office to reduce the risk of exposure to PM2.5 during our daily life and work.
